How do I disable http?

I'm running apache 2.0.55 and I'm trying to figure out how to disable http so I can only use https. Currently going to my ip from http:// and https:// yields the same results but I only want to use https.

this seems like a pretty simple question, but I haven't been able to find anything out looking through google...Is this an apache option or an OS option? I'm running a freebsd system.
